We bought one of these displays from CarTFT in Germany for my sons CarPC in his FTO and all worked fine until it came to the touch screen.
The cursor continually moves to the center top of the screen.
If you move the cursor to half way down the screen using the mouse then its its fine with the touch screen again until you get near the top of the screen when it again jumps to the screen top center. You can move the cursor with the touch screen but as soon as you take your finger off it jumps back to the top cener again.
We have tried everthing we can think of including the latest drivers from Lliyitek's web site but still can't resolve the problem.
I am starting to think its a hardware fault.
Anyone seen something similar?
I hope the explanation made sense.
